Helping theology matter

Several years ago, in the midst of one of its well-publicized battles about sex, the Presbyterian Church (U.S.A.) proclaimed, "Theology matters." At first glance, this was a slogan to warm the heart of a theologian. But then I started to wonder why our denomination even had to say such a thing. After all, theology means thinking about our faith, and for Christians our faith ought to lie at the core of our lives. So why wouldn't theology matter?
